Article 450 - Appeals--in What Cases Authorized and to What Courts Taken
450.90 - Appeal to Court of Appeals From Order of Intermediate Appellate Court; in What Cases Authorized.

(a) The court of appeals determines that the intermediate appellate
court's determination of reversal or modification was on the law alone
or upon the law and such facts which, but for the determination of law,
would not have led to reversal or modification; or
(b) The appeal is based upon a contention that corrective action, as
that term is defined in section 470.10, taken or directed by the
intermediate appellate court was illegal.
